8051 - Standard
SFR Descriptions

This
section
will
endeavor
to
quickly
overview
each of
the
standard
SFRs
found in
the
above
SFR
chart
map. It
is not
the
intention
of this
section
to fully
explain
the
functionality
of each
SFR--this
information
will be
covered
in
separate
chapters
of the
tutorial.
This
section
is to
just
give you
a
general
idea of
what
each SFR
does.
